DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to illustrate the structural features and effects of the present invention more clearly, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 3 , an electric inflatable bed with multiple air chambers according to an embodiment of the present invention includes an inflatable bed body 1. The inflatable bed body 1 includes a main air chamber 101, an upper air chamber 102 and a lower air chamber 103. The main air chamber 101 is equipped with the upper air chamber 102 and the lower air chamber 103 at its top and bottom. The main air chamber 101, the upper air chamber 102 and the lower air chamber 103 are respectively arranged separately. One side of the upper air chamber 102 is further fixedly equipped with an upper airtight sheet 106, and one side of the lower air chamber 103 is further fixedly equipped with a lower airtight sheet 107. One sides of the main air chamber 101, the upper air chamber 102 and the lower air chamber 103 are further equipped with a main air chamber air hole 109, an upper air chamber air hole 110 and a lower air chamber air hole 111, respectively. The electric inflatable bed further includes an inflator pump assembly 2. The inflator pump assembly 2 includes a pump casing 201, an operation panel 202, an on-off switch 203, a drive motor 205, a ventilation cylinder 207, a guide channel 208 and a main air passage 209. One end of the pump casing 201 is fixedly equipped with the operation panel 202. The operation panel 202 is rotatably equipped with the on-off switch 203. The operation panel 202 is further provided with vent holes 204. The ventilation cylinder 207 is assembled inside the pump casing 201 and connected with the vent holes 204. The drive motor 205 is fixedly arranged in the pump casing 201 and connected with an impeller 206 at its end. The main air passage 209 is arranged on one side of the pump casing 201 and connected with the ventilation cylinder 207 through the guide channel 208. An air-sealing plate 212 is further movably inserted at one side of the main air passage 209. A connecting hole 108 is further arranged on one side of the main air chamber 101 to position and assemble the inflator pump assembly 2.

In the practical application of this embodiment, during the use of the electric inflatable bed, the inflatable bed body 1 in the inflatable bed is divided into three parts: the main air chamber 101, the upper air chamber 102 and the lower air chamber 103. The main air chamber 101, the upper air chamber 102 and the lower air chamber 103 are arranged separately, and the inflator pump assembly 2 can be used to inflate and deflate the main air chamber 101, the upper air chamber 102 and the lower air chamber 103 separately. The pump casing 201 is assembled in the connecting hole 108 on one side of the main air chamber 101, and the main air passage 209 at one end of the pump casing 201 is connected with the main air chamber air hole 109. The side air passages 210 connected on two sides of the main air passage 209 and two branch pipes 211 connected with the two side air passages 210 are respectively connected with the upper air chamber air hole 110 and the lower air chamber air hole 111. When the inflator pump assembly 2 acts for inflating, the drive motor 205 inside the pump casing 201 is controlled to rotate in a fixed clockwise direction by rotating the on-off switch 203 on the surface of the operation panel 202 and during the rotation process, the impeller 206 is driven to rotate. The impeller 206 rotates to agitate the air, and discharges the air toward the side of the main air passage 209, so that the air passes through the main air passage 209 and the pump casing 201 and is output to the main air chamber air hole 109, the upper air chamber air hole 110 and the lower air chamber air hole 111 respectively, and the main air chamber 101, the upper air chamber 102 and the lower air chamber 103 are inflated separately. When the impeller 206 rotates, due to the negative pressure generated inside the pump casing 201, the outside air can pass through the vent holes 204 provided on the outer side of the inflatable bed and enter into the ventilation cylinder 207 and then pass through the guide channel 208 connected with the ventilation cylinder 207 to flow into the main air passage 209, thus forming a continuous inflation action. The same principle is true for the deflation process. The main air passage 209 and the branch pipes 211 that are separately connected to the main air chamber 101, the upper air chamber 102 and the lower air chamber 103 can be used to electrically pump the air out of the inflatable bed. In this way, inflation and deflation can be carried out conveniently and quickly.

In one case of this embodiment, the main air chamber 101, the upper air chamber 102 and the lower air chamber 103 are arranged separately, so that the edges of the inflatable bed have higher compressive strength. For the traditional inflatable bed with a single air chamber, when an edge of the bed body is pressed, the air at the edge tends to move toward the middle of the bed body, resulting in insufficient support on the side edge and easily causing the user to miss his step and slip off. Compared with the traditional inflatable bed with a single air chamber, this embodiment adopts multiple air chambers so that the air chambers push against each other. When a side edge is pressed, the movement of the air toward the middle of the bed body can be effectively reduced, so as to ensure that the air in the side of the bed body can provide a stable support.

As shown in FIG. 1 , in a preferred embodiment of the present invention, an upper diagonal-pulled sealing sheet 104 is further assembled and connected between the upper air chamber 102 and the upper airtight sheet 106, a lower diagonal-pulled sealing sheet 105 is further assembled and connected between the lower air chamber 103 and the lower airtight sheet 107, the main air chamber 101, the upper air chamber 102 and the lower air chamber 103 are further provided therein with independent supporting sheets 112, and a plurality of independent supporting sheets 112 are assembled in array among the main air chamber 01, the upper air chamber 102 and the lower air chamber 103.

In practical application of this embodiment, the upper diagonal-pulled sealing sheet 104 and the lower diagonal-pulled sealing sheet 105 are respectively used to connect the upper air chamber 102 and the upper airtight sheet 106 and the lower air chamber 103 and the lower airtight sheet 107. In this way, the sealing effect can be enhanced and the air tightness between the upper air chamber 102 and the upper airtight sheet 106 and between the lower air chamber 103 and the lower airtight sheet 107 can be ensured.

In one case of this embodiment, a plurality of independent supporting sheets 112 are arranged in array in the main air chamber 101, the upper air chamber 102 and the lower air chamber 103. The independent supporting sheets 112 can assist in improving the support strength of the bed body so that the inflatable bed has better compression resistance.

As shown in FIGS. 1 to 3 , in a preferred embodiment of this embodiment, the main air passage 209 is assembled on and connected with the main air chamber air hole 109. The inflator pump assembly 2 further includes side air passages 210 and branch pipes 211. The side air passages 210 are arranged at two ends of the main air passage 209 and connected with the two branch pipes 211 respectively.

In practical application of this embodiment, the main air passage 209 is connected with the main air chamber air hole 109, and the two branch pipes 211 are respectively connected with the upper air chamber air hole 109 and the lower air chamber air hole 111. Through the rotation of the impeller 206, the pumping action can be continuously performed, and the air can be delivered to the main air chamber 101, the upper air chamber 102 and the lower air chamber 103, respectively.

In one case of this embodiment, the air-sealing plate 212 is flexibly inserted on one side of the main air passage 209 to seal the main air passage 209. When the inflator pump is in an off state, the air-sealing plate 212 flexibly pushes against the main air passage 209 for sealing by default. During the pumping action, the ventilator cylinder 207 can push the air-sealing plate 212 outwards when rotating along with the on-off switch 203, so that the air-sealing plate 212 is away from the side of the main air passage 209.

The above-mentioned embodiment of the present invention provides an electric inflatable bed with multiple air chambers. By virtue of the inflator pump assembly 2 assembled on one side of the inflatable bed body 1, the multiple separate chambers inside the inflatable bed body 1 can be connected, and the pumping action can be carried out separately for the multiple chambers. In this way, the inflatable bed can shrink quickly and electrically, and also the assembly structure of multiple chambers is adopted to improve the support strength of the edge portions of the inflatable bed and further effectively improve its safety performance.
